How to Adjust the Valve Clearance of Tiggo 3?

Tiggo 3 valve clearance adjustment method: 1. Preheat the engine until the coolant temperature reaches 80 degrees Celsius, open the timing mark inspection hole on the clutch housing and the cylinder head cover, and ensure that the cylinder head bolts are tightened to the specified torque; 2. Rotate the crankshaft to align the 0 mark on the flywheel with the mark line on the clutch housing, confirm that the curved surface of the intake and exhaust valve rocker arms of the first cylinder is in contact with the base circle of the camshaft cam, that is, the first cylinder piston is at the compression top dead center, and the valves are in the closed position at this time; 3. Loosen the lock nut 2 of the adjustment screw 1, use a screwdriver to turn the adjustment screw so that the gap A between the lower end face of the screw and the upper end face of the valve stem 3 is the specified clearance value, keep the screwdriver still, tighten the lock nut to the specified torque, and then use a feeler gauge to insert into gap A for rechecking. This way, the intake and exhaust valve clearances of the first cylinder can be adjusted; 4. Rotate the crankshaft clockwise. For a 4-cylinder engine, every 180 degrees of rotation, the valve clearance of the next firing cylinder can be adjusted in the ignition order of 1, 3, 4, 2. For a 3-cylinder engine, every 240 degrees of rotation, the valve clearance can be adjusted in the ignition order of 1, 2, 3.

Should the Lynk & Co use 92 or 95 gasoline?

According to the official vehicle manual recommendation, the Lynk & Co should use 95-octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will be clearly marked. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. Even high-compression engines can be tuned to use lower-octane gasoline. This is because factors other than the compression ratio also play a role, such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Lynk & Co occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance as experienced in real-world driving. For vehicles recommended for higher-octane gasoline, using lower-octane gasoline can cause engine knocking. Because the octane number is significantly lower, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise and does not significantly damage the engine. However, noticeable knocking indicates severe engine conditions, where vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.

How many points are deducted for making a U-turn on a solid yellow line?

Making a U-turn on a solid line is a traffic violation. According to Article 93 of the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 penalty points. Generally, on long roads, solid white lines are often found in the middle section or before intersections. If the lines are yellow dashed or white dashed, U-turns are allowed. However, U-turns are strictly prohibited on any solid lines. Situations where U-turns are allowed: If there is a clear U-turn sign at the intersection, U-turns are permitted. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, make a U-turn based on the specific situation, ensuring it does not obstruct other vehicles or pedestrians. U-turns are allowed at intersections without explicit "No U-turn" or "No Left Turn" signs: If there is no clear prohibition, U-turns are permitted. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No Left Turn," or solid center lines, allowing confident U-turns. U-turns are also allowed on yellow grid lines: Yellow grid lines are no-parking zones marked at intersections prone to congestion, important entrances, or other designated areas. Stopping on these lines (including waiting at traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed. If there is no central barrier, yellow grid lines are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn light, follow it; U-turns are only allowed on green. When "No Left Turn" and "U-turn Permitted" signs appear together: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Things to note when making a U-turn at an intersection: Observe road markings—if they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are not allowed at that intersection because U-turns inherently involve left turns. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles. Make a U-turn only if it does not interfere with their normal flow; otherwise, you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—if it has a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs. U-turns on crosswalks are also violations.

What Causes Rust on Car Brakes?

Rust primarily depends on the material of the brake disc. If rust appears on the car's brake disc, it may be due to exposure to water or a humid environment. Since car brake discs are made of cast iron, they can develop surface rust after the car is parked for a while under conditions such as car washing, driving in rainy weather, wading through water, driving on snowy roads, frost, or in high-humidity environments. This is a normal phenomenon of oxidation and rusting when cast iron components come into contact with water. Brake discs require sufficient friction to function effectively, so they are not treated with any anti-rust coatings. If the brake disc only has slight surface rust, it can be removed by continuously applying the brakes while driving. The friction between the brake caliper and brake pads can eliminate the surface rust, restoring the brake disc to its original condition. However, ensure safety by performing this operation in a safe area. If the brake disc is severely rusted, it needs to be polished at a 4S shop or auto repair shop to remove the rust. Rust on the brake pads does not affect braking performance. The rust can easily be worn off by lightly applying the brakes while driving. Initially, there might be a squeaking sound, but it will disappear after driving a few kilometers and applying the brakes a few times. Even if the car is left unused for an extended period, there is no need to worry about the brake pads rusting excessively. If the parking location is dry, rust is even less likely to form. Braking primarily relies on the brake disc, caliper, and brake pads, with the brake pads being the most worn component. As long as the brake pads are not worn beyond their limit and the brake fluid is not deteriorated, driving safety is generally not affected. The car brake system, also known as the car braking system, functions to: decelerate or stop a moving car as required by the driver; keep a parked car stable under various road conditions (including on slopes); and maintain a stable speed for a car driving downhill. If the car remains parked for a long time without use, it is recommended to drive it every two months and apply the brakes. This helps maintain the brake discs and prevents severe rusting that could affect braking performance.

Can I apply for ETC for a car not under my name?

It is possible to apply for ETC even if you are not the owner of the car. According to the "Implementation Plan for Accelerating the Application of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and a copy of the vehicle registration certificate (the page with the latest annual inspection stamp) are required. If you are applying on behalf of someone else, you also need to provide the original valid ID card of the agent. If you apply for ETC through major bank branches, you will also need to prepare a debit card or credit card from the corresponding bank. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. ETC charging principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle accounts with the bank in the background, achieving the purpose of paying road and bridge tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: eliminates the hassle of queuing and waiting; Green and environmentally friendly: green and low-carbon, vehicles pass through the toll station without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduce wear and tear: saves costs, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on toll fees; Improve efficiency: the efficiency of passing through ETC lanes can theoretically be increased by 2-3 times, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "Development Plan for the Modern Comprehensive Transportation System during the 13th Five-Year Plan" that "by 2020, the interoperability of transportation cards in key urban agglomerations will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of comprehensive transportation development during the 13th Five-Year Plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate of passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with the development directions of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means that more application scenarios will support ETC applications. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front that has stopped, to prevent the ETC device of the vehicle in front from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for passing through ETC lanes is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized disassembly or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. You can send it to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not caused by human factors, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in a failed fee deduction. You can follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. If the car windshield is too thick, it may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.
